ATP-Series High Power Timing Belts
ATP-Series High Power Timing Belts
ATP-Series timing belts are heavy-duty polyurethane synchronous belts engineered for the highest power transmission capacity in the polyurethane timing belt range. They feature a wider, deeper tooth profile than the standard AT-Series, distributing load across a larger contact area to deliver approximately 30% to 50% more power capacity at the same pitch and width. ATP belts require ATP-specific pulleys and are not interchangeable with standard AT pulleys.
Texas Belting stocks ATP-Series belts in ATP10 (10mm) and ATP15 (15mm) pitches. Both are available in open-ended rolls, welded endless loops, and truly endless molded configurations. All ATP belts feature steel cord tension members and support the full range of backing options and machined modifications.
- Pitches: ATP10 (10mm), ATP15 (15mm)
- 30% to 50% more power than standard AT at same pitch
- Wider, deeper tooth profile for maximum load transfer
- Widths: 25mm to 150mm
- Configurations: open-ended, welded, truly endless
- Tension members: steel cord (standard), stainless, aramid
- Requires ATP-specific pulleys (not AT-compatible)
- Temperature range: -30°C to +80°C (+100°C with Gen III)
ATP10: 10mm Pitch
ATP10 belts deliver near-AT20 power capacity while using AT10-sized pulleys. This makes ATP10 the right choice when a drive needs significantly more power than standard AT10 can provide but the layout cannot accommodate the larger pulleys required by AT20 or ATS15.
| Configuration | Available Widths (mm) | Details |
|---|---|---|
| Open-Ended | 25, 32, 50, 75, 100 | Sold per meter, cut to length |
| Welded | 25, 32, 50, 75, 100 | Custom endless lengths |
| Truly Endless | 25, 32, 50, 75, 100 | Standard pitch lengths available |
ATP15: 15mm Pitch
The maximum power capacity option. ATP15 belts handle the heaviest torque loads in the polyurethane timing belt range and are specified for large machinery, heavy conveying, and industrial press drives where nothing less will do.
| Configuration | Available Widths (mm) | Details |
|---|---|---|
| Open-Ended | 25, 32, 50, 75, 100, 150 | Sold per meter, cut to length |
| Welded | 25, 32, 50, 75, 100, 150 | Custom endless lengths |
| Truly Endless | 25, 32, 50, 75, 100, 150 | Standard pitch lengths available |

| ATP15 | 20 | 30 | 100mm | 160mm |
ATP vs. AT vs. ATS15: Choosing the Right Heavy-Duty Belt
Three belt series target heavy-duty power transmission applications, each with a different approach to maximizing power capacity. The table below compares them to help you select the right belt for your drive requirements.
| Property | AT-Series | ATP-Series | ATS15 |
|---|---|---|---|
| Approach to higher power | Standard tooth at larger pitch | Wider, deeper tooth at same pitch | Larger pitch (15mm) with symmetric tooth |
| Available pitches | AT3, AT5, AT10, AT20 | ATP10, ATP15 | 15mm only |
| Power gain over AT10 | Use AT20 for ~2.5x | ATP10: 1.3x to 1.5x | ~2x |
| Pulley compatibility | AT pulleys | ATP-specific pulleys | ATS15-specific pulleys |
| Key advantage | Widest pitch range, most common | More power without larger pulleys | Maximum torque at 15mm pitch |
| Best for | Standard to heavy drives | Space-constrained heavy drives | Heavy drives with room for 15mm pulleys |
Common Applications
ATP-Series belts are specified for the most demanding industrial drive applications where standard AT belts reach their power limits. Typical equipment includes heavy-duty conveyor systems, steel mill auxiliary drives, industrial press drives, large injection molding machines, heavy CNC machine spindle and axis drives, sawmill carriage drives, and high-load material handling gantry systems.
For conveying applications requiring ATP-level power, belts can be fitted with welded profiles and backing materials. For heavy-duty pulleys to match, see the high precision pulleys and stock pulleys pages.
Frequently Asked Questions
ATP belts use a wider, deeper tooth profile that distributes load across a larger contact area than the standard AT-Series tooth. This delivers approximately 30% to 50% more power capacity at the same pitch and width. The trade-off is that ATP belts require ATP-specific pulleys and cannot be used on standard AT pulleys.
The ATP series is available in two pitches: ATP10 (10mm) and ATP15 (15mm). Both are designed for heavy-duty power transmission where standard AT belts have reached their load limits.
No. ATP belts require ATP-specific pulleys with a matching wider tooth groove. The ATP tooth profile is wider and deeper than the standard AT profile, so standard AT pulleys will not provide correct tooth engagement. ATP pulleys are available from Texas Belting in aluminum, steel, and stainless steel. See the stock pulleys page or call 888-203-2358 for availability.
Choose ATP10 when the drive layout cannot accommodate the larger pulleys required by AT20 (20mm pitch). ATP10 delivers near-AT20 power capacity while using AT10-sized pulley diameters, keeping the overall drive footprint compact. If space is not a constraint, AT20 or ATS15 are typically more cost-effective options for achieving higher power capacity.
Yes. Both ATP10 and ATP15 belts are available in open-ended rolls (cut to any length), welded endless (custom loop lengths), and truly endless (molded continuous loop for maximum strength). All standard backing and modification options are available for ATP belts.
ATP belts are used in heavy industrial applications including steel and metals processing, industrial press drives, large conveyor systems, heavy machine tool drives, injection molding machine clamping drives, sawmill equipment, and high-load material handling systems.
Standard ATP belts operate from -30°C to +80°C. The Redflex GEN III compound extends the continuous operating range to +100°C. For guidance on extreme temperature applications, contact Texas Belting at 888-203-2358.
In many cases, yes. ATP timing belts offer significant advantages over roller chain for heavy-duty drives: no lubrication required, no chain stretch or re-tensioning, lower noise, and cleaner operation. The high power capacity of ATP belts makes them a viable replacement for roller chain in applications up to the rated capacity of the belt. Contact Texas Belting for a chain-to-belt conversion evaluation for your specific drive.
